It is my 2nd wedding. I have 3 beautiful kids.

It's his first and wants the traditional day. He wants all of our family and friends and darn it, I am wearing white.

My issue lies with bridesmaids. I had my sisters before. This time I wanted friends but frankly, everyone is just plain busy. We all live a small distance apart - the farthest being about 2 hours away. We all have kids, work full time, etc. I've already asked two of my girls and just emailed the one stressing because who knows when I'll be able to ask the others and I gotta be honest - it feels daunting. I was so excited and now I just feel like I'd be better off with my daughters and then all of his groomsmen. Would that look/be weird? Or should I ask my girls and just do the best I can to get them together and involved? I don't want my wedding to be a bad time for anyone. I've been in enough to know what to do and not to do and now, I am stuck.
Any advice?
Thanks!
